T all whom it may c017v 0cm:

Be it known that I, GEORGE R. Moon, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ovens, of which the following is a specification.

My invention relates to ovens and has for its object the provision of a device of this character constructed in such manner that the bottoms of the shelves upon which articles to be baked are placed, are protected from the direct action of the heat and said heat .is caused to enter the compartments from the top, by virtue of which construction the material to be baked is as thoroughly cooked around its edges as at the center.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing: Figure 1 is a perspective view of an oven constructed in accordance with the invention, with the door of said oven broken away, Fig. 2 is a transverse vertical section through said oven, Fig. 3 is a longitudinal vertical section upon line of Fig. 2, and Fig. 4. is a detail horizontal section through one corner of the oven.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing, the numerals 5 designate the side walls of the oven, the numeral 6 designates the top wall, the numeral 7 designates the rear wall and the numerals 8 designate strips of metal located at the front of the oven and forming substantially door jambs. A door 9 is hinged to one of these strips as at 10 and is adapted to close the front of the oven.

A compartment 11 is formed at the upper part of the oven by a plate 12, this plate having a row of centrally located holes 13 formed therein extending from the front of the oven to the rear thereof. A flue collar 14 adapted to have a flue slipped thereupon, leads from the compartment 11. A lower shelf 15 and an upper shelf 16 are provided with upwardly extending side walls 17. These side walls extend from the door jambs 8 to the rear wall of the oven. The side walls 17 and the baffle plates 21 are formed in one piece and these side walls are riveted at each end to angle plates 30. These angle plates carry lugs 31 which support the shelves 16. hen these shelves are placedin position and forced downwardly, the side walls and the angle plates to which the side walls are riveted, are spread apart and bound against the sides of the oven. I t will therefore be seen that the angle plates, the shelves. the side walls of the shelves, and the baffle plates are held in p0- sition without being riveted to the walls of the oven. A V-shaped spreader 22 is secured to the bottom of the shelf 15 and protects said shelf against the direct action of heat from a gas burner 23, said burner being of any desired construction, but extending substantially the full length of the oven.

The operation of the device is as follows: hen gas from the burner is ignited, the heat products from said burner travel up the sides of the oven, some of the heat being directed by the bafIle plates 21 over the side walls of the shelf 15 and some of the heat passing u wardly and being directed by the baff e plates 20 over the sidewalls of the upper shelf 16 and into the upper and lowercompartments of the oven. The material to be baked, it will therefore be seen, is effectually rotected against the direct action of heat from the burner 23. \Vhere walls such as 17 are not provided, the heat passes directly over the edges of the shelves and strikes first against the edges of the material that is being baked and burns this material around its edges, before the center is thoroughly cooked. These side walls protect the material being baked against such action as this and the baffle plates direct the heat over toward the center of the compartments, the result being that the material is as thoroughly cooked at its center as at its edges. No heat can escape from the oven except through the centrally located openings 13. The heat must travel to the center of the oven above the upper com )artment, therefore, before it can escape. t passes through the openings 13 to the compartment 11 and thence to the flue.

From the foregoing description, it will be seen that simple and efficient means are herein provided for accom )lishing the objects of the invention, but whi le the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

\Vhat I claim, is:

1. An even comprising an outer shell, an upper shelf and a lower shelf located centrally within said oven, side walls carried by said shelves upon each side thereof, said side walls being spaced from the side walls of the oven, a flame spreader located beneath the lowermost shelf, a burner located beneath said flame spreader, a baffle plate located at each side of the upper shelf and directed diagonally downward to direct heat from the burner inwardly over the side walls of the lower shelf, a compartment located at the top of the oven, baffle plates located at each side of the oven and arranged to direct heat from the burner inwardly over the upper edges of the side walls of the upper shelf,

there being a centrally located means of communication between the oven and the upper compartment and a flue leading from'the upper compartment.

2. An oven comprising an outer shell, an

upper shelf and a lower shelf located centrally within said oven, side walls carried by said shelves upon each side thereof, said side walls being spaced from the side walls of the oven, a flame spreader located beneath the lowermost shelf, a burner located beneath said flame spreader, a baflie plate located at each side of the up er shelf and directed diagonally downwar to direct heat from the burner inwardly over the side walls of the lower shelf, a com artment located at the top of the oven, ba e plates located at each side of the oven and arranged to direct heat from the burner inwardly over the upper edges of the side walls of the upper shelf, there being a centrally located means of communioation between the oven and the upper compartment and a flue leading from the u per compartment, vertically extending ang e lates to which the side walls are secured and ugs carried by said vertically extending an gle plates adapted to sup ort the shelves.

In testimony whereof Faflix my signature in presence of two witnesses.

GEORGE R. MOON.
